MECHANISM FOR DRIVING HAND-CARS.

QPECIFICATION forming part of Letters Patent No. 34:4,163, dated June22, 1886.

Serial No. 130,957. (No model.)

To all whom it may concern:

Be it known that I, FERDINAND E. CANDA, of the city, county, and Stateof New York, have invented a new and Improved Mechanism for DrivingHand-Oars and for otherPurposes, of which the following is a full,clear, and exact description.

My invention relates to the construction of an improved mechanism fordriving handcars, and its object is to produce a mechanism by which acar may be driven at an exceedingly high rate of speed by means of theordinary hand-power employed to propel such cars; and to this end myinvention consists of a system or series of links or levers united inthe form of a lazy-tongs and arranged to be extended and contracted toimpart a rotary movement to the crank-shaft, said movement of thelazy-tongs system being brought about by means of a double-armedhand-lever,which is mounted on a central connecting-bolt of the seriesof levers and connected by a novel arrangement of links with the outercentral joi nts.

of said levers.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an end view of a handcar provided with my improved drivingmechanism. Fig. 2 is a side view of the car, with a portion of thesupporting-frame removed to show the various parts of the drivingmechanism,which in this view are represented in the position they assumeon the full downstroke. Fig. 3 shows the position of the parts on thehalfstroke, and Fig. 4 on the full upstroke.

The hand-car proper is of the ordinary type, such as is used on thePennsylvania Railroad, of which the general construction is so wellknown that it is unnecessary to go into any description thereof. A framecorresponding to the ordinary form of lever-frame, only the frame inthis case is slightly higher than usual, and is located directly overthe crankshaft A, is formed by four corner-posts, B B, which are fixedto the floor-bean1s and united at their upper ends by a cap, 0, which ishollowed out in pyramidical form and supports a bearing-block, D, Ashort rod or bolt, E, is mounted in bearings a a, formed in the block D,and this rod carries the four upper links,

I) I) and c c, of the driving mechanism, the links being separated andspaced by washers ii, and the links I) I) being between the links 0 a.Each pair of links. carried by the rod E carries a pair of links, suchas those shown at (Z d and c c, the connections being made by means ofbolts ff, which are passed through apertures formed in the ends of thelinks, the links 0 0 being outside of the links Z) I), while the links(I d are inside of or between the links 0 c, the bolts ff carryingwashers between the links, as in the case of the rod or bolt E, and itmay here be said thatin allcases I prefer to space the links by washers.The links (I d and c c are crossed, the links (1 cl being carriedbetween the links 0 e, and the two sets of links are, as it were,pivotally connected at their centers by what I will call the mainconnecting-bolt F.

To the extending ends of the links 0 e and (Z d, I connect the lowerseries of links, H H and h h, by means of bolts 9 g, and the links it hare loosely fixed to the links H H by a bolt, k, the attachment beingmade at a point so that the distance from tog will be equal to thedistance from 7; too. Thelinks H H serve the double office of links inthe lazy-tongs system and of connecting-rods between such system and thecrank J of the shaft A, which shaft is,as usual,mounted in bearingscarried by the floor-beams. The shaft A carries a large geanwhecl, K,which engages with a pinion, N, that is fixed to the axle M of the driving-whcels O 0.

Upon the bolt F there are mounted the central arms, Z Z, of the doublehand-lever L L, the said central arms being rigidly fixed to or madeintegral with the outer arms, Z Z, which carry the handles m in.

The arms Z Z are provided with bolts 11, or upon each side of thecentral bolt, F, said bolts a a being placed at like distances from thecentral bolt, which distance is equal to onehalf the length of the links6 and 01. These bolts not carry short links 0 0 and 0 o, respect ively,similar links, 1) p and p 1), being can ricd by the bolts f and g of thelazytongs system. The free ends of the links 0 o and 12 p are connectedby a link, g, which is formed with a central lug, to which there ispivotally connected a pair of links, r 9, which reach to and are looselyheld by the boltf, while the free ends of the links 0 0' and p p areconnected by a second link, 8, which is a duplicate of the link q, beingformed with a central lug, s, and connected to the bolt 9 by links r 1".

From the arrangement of connecting parts, as above described and asillustrated in the drawings, it will be seen that the lever L L isconnected by means of links to each of the four outer central joints ofthe power-transmitting mechanism, and that the central bolt of the saidpower-transmitting mechanism becomes the fulcrum of the lever throughwhich the power is applied, so that the hand-lever follows the generalswing of the lazy-tongs system upon its upper supporting-bolt, E, and isconsequently always in position to act upon such system through themedium of its connecting-links.

In operating my improved driving mechanism the handles m m of the leverL L are grasped, and if the crank is in the position shown in Fig. 4 thehandle m is lowered, which movement will cause the projecting ends ofthe links 0 0 and p p to rise and the corresponding ends of the links 00 and p p to be lowered, thereby driving the links q and s closer to thepoints a f and n g, respectively; but to bring about this movement ofthe links q and s the links 1' 7' must also be moved toward the pointsnamed, and consequently the points f and f will approach, as will alsothe points 9 g. In other words, the lazy-tongs system' will be extendedand the crank-shaft moved to the position shown in Fig. 2. WVhen themotion of the levers L L is reversed, the movement of the links q and swill also be reversed, and at the half-stroke of the lever the partswill be in the position shown in Fig. 3,

a continued movement carrying the parts to the position shown in Fig.4,-the movements described and indicated being repeated at eachfull-stroke of the driving-lever.

With. the system described there is no undue strain on any one of thepivoted joints, as the power is equally distributed; but in some casesit would not be necessary to have all four of the points f f and g 9connected with the lever L L, as the power could be ap plied to thepoints ff through the links 0, p, q, and 1'; but I prefer to distributethe power to all four of the connecting-points.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isi 1. An improved driving mechanism,consisting of a lazy-tongs system, wherein the powerlever arm is mountedupon and supported by the central pivot or bolt of the system, and con--nected, by mesne connections, to the outer central joints of the system,substantially as described.

2. An improved driving mechanism, consisting of a lazy-tongs system,wherein the powerlever arm is supported by the central bolt of thesystem, and connected by links, in a man ner substantially as described,with the four outer central joints of said system, substantially as setforth.

3. The combination, with the crank-shaft and lazy-tongs system,substantially as described, of a lever, L, and links 0, p, q, and r,substantially as set forth.'

4. The combination, with the crank-shaft frame and the lazy-tongs systemsuspended and held by the bolt E, of a lever, L, links 0,

p, q, and r, and a crank-shaft, substantially as set forth.
